Abstract: People living in rural areas of Liuyang, Hunan province were selected to query to investigate the exposure factors. The results showed that the average body weight of adult males and females in this area were 62.45and 53.71kg, respectively, with the average body surface area 1.710and 1.546m². Average daily drinking water intake of adults in the area was about 1248mL, with a 95^th percentile value was 3350mL, while the average amount of direct water intake was 1035mL and the 95^th percentile value was 2500mL. The average amount of daily rice intake, wheat flour, fish, pork, chicken, eggs for adult males were 335.54,9.28,5.41,8.48,4.18and 21.70g, respectively, while the values for females were 269.28,8.45,4.89,6.73,3.11,8.07g, respectively. We also found that the spring water and underground water were the main sources of drinking water for them, the percentage of which accounted for 52.42% and 36.31%, respectively. The surface water (e.g, rivers and lakes) was also used as their drinking water by a part of residents. Exposure factors of adults in this area were quite different from that recommended from the handbooks of the USA and Japan. In addition, some differences were also found, compared with similar studies of USA and Japan, and this indicated the existence of regionality and ethnicity for the exposure factors.
